Area of Science:

  • Psychology
  • Behavioral Science
  • Health Psychology

Background:

  • Understanding sociopsychological factors is crucial for effective weight management.
  • Previous research has explored various predictors of weight loss with mixed results.

Purpose of the Study:

  • To investigate the sociopsychological predictors of weight loss using multivariate analyses.
  • To identify key factors influencing actual weight loss in a comprehensive program.

Main Methods:

  • Utilized a theoretical framework with multiple variables.
  • Employed multivariate analyses including factor, multiple regression, and path analyses.
  • Analyzed data from 309 participants in a weight-loss program.

Main Results:

  • Self-assurance emerged as the most significant predictor of weight loss.
  • Weeks completed in the program was the second most important predictor.
  • Program satisfaction and perceived importance indirectly influenced weight loss via self-assurance and weeks completed.

Conclusions:

  • Self-assurance and program adherence are vital for successful weight loss.
  • Distinct predictors were observed for program completers versus dropouts.
  • Findings offer implications for professionals in weight control and behavioral intervention design.
